Resume
Mandible biomechanics implication of new traversodontides eucynodontes from the Triassic ofMadagascar: Menadon besairiei et Dadadon isaloï, via analysis of correlation between structure and function, and application of Bramble (1978) bifulcral method, shows evidence of following properties: (i) ability of both animal to realize bilateral dynamic occlusion between upper and lower jugal teeth in posterodorsal direction – (ii) This dental occlusion works with more crushing function by a mortar and pestle system in Menadon which needs high biting force. On the other hand, Dadadon dental occlusion
